To all whom it may concern.-

Be it known that I, HERBERT F. 0001;, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a certain new and useful Improvement in TubularBoilers, of which the following is a full, clear, and exact description, reference being had to,the accompanying drawings.

The object of the invention is to provide a boiler in which steam may be quickly and economically made.

To that end the invention consists in the construction and combination of parts shown in the drawings and hereinafter described whereby extensive heating-surfaces are presented to the action'of the heat and the water is allowed'to circulate very freely through the parts whose surfaces are thus exposed to the action of the heat, allof which will be definitely pointed out in the claims.

In the drawings, Figure 1 is 'a front view of the boiler with parts 'of the protecting front plate removed. Fig. 2 is a side view when the side of the .brick casing is removed. Fig. 3 is an end view, partly in section, of two of the headers of which the boiler ends are composed. Fig. 4 is a side View. of one of said headers; and Fig. 5 is a transverse sectional view on line 5 5 of Fig. 2, showing one of the deflecting-plates.

Each end of the boiler, is made up of a group of vertical hollow headers A A, which are set side by side or nested, substantially as shown. Each header has in its inner face the tube-holes a a, which are arranged in two vertical rows, substantially as shown, the holes in one row being staggered with re spect to those in the other row. All of the holes in one vertical row have a downward inclination, while those in the other row have an upward inclination. These holes a and a respectively receive the ends of the tubes B and B, which ends inside the headers are upset in the usual manner. The tubesB in one vertical row are inclined from the horizontal in' one direction while the tubes in the adjacent vertical row are inclined in the opposite direction. The outerwalls of the headers have holes a in line with those in their inner walls, which holes are closed in a suitable manner, as by theheader-plates a held by crabs a and nutted bolts a The tube-holes a a in the headers are so placed that the tubes in the two vertical rows will substantially touch when they pass one another. (See Fig. 5.) In order that this condition may exist with respect to the adjacent tubes attached to different headers, the headers are made of the sinuous form shown; but the adjacent sides of adjacent headers are of complementary form, whereby they nest together, as shown, and fit tightly against one another. Each header is connected at both its upper and lower ends with the two headers whichlie at its sides, these connections being made by the tubes 0, which fit in holes a? in the side of the headers and havetheir inner ends upset,

as shown. Each header is connected by a respectively, and these extensions are con 7 nected, as shown, bythe four vertical pipes I-I. At each end of the dome E, which overhangs the brickwork, is a downwardlyextended pipe J, outside the brickwork, which is connected with a horizontal pipe K, and this horizontal pipe is connected at the ends with I the lateral extensions G at the lower ends of the outside headers.

The steam-dome N is supported above the water-dome and is in open communication therewith.

It is a well-known fact that steam does not form from vertical heating-surfaces, and in my construction it will beobserved that the pipes J are vertical. This is evidently a great advantage, as the steam which necessarily forms in inclined pipes impedes the downward flow of the circulating water. Now, as

the pipes J are vertical and they, with the pipes communicating with their lower ends,

are removed from the heat of the fire, the circulation of the water must be greatly facilitated. In operation the steam forming in the heating-pipes flows directly to either header and is immediately replaced by water rising through the opposite header. The rising water in the headers is supplied by the horizontal pipes K, which in turn receive their water from the vertical pipes J. Evidently the circulation in a boiler constructed so that the vertical pipes and their communicating pipes were within the brick housing and under the influence of the fire would still possess many advantages over ordinary boiler types. Hence I do not confine myself to any particular location of the vertical pipes J nor to any particular form of boiler.

The inclosing shell F for the boiler, as described, may be built up from bricks,as shown, or may be made of any other suitable material. Beneath one end of the tubes B B, within the shell, is the grate M, and above the other end of said tubes is the stack P. To cause such circulation of the heat as will render it most efiective, the space within the shell is divided by vertical partitions R and T, which are made up of independent plates 0 and 25. These plates have notches r and t in their upper and lower edges, nearly semicircular in form, and when the plates are turned up into vertical position they lie in the vertical plane in which the oppositely-inclined tubes pass one another, and they engage with said tubes and substantially fill the space between the tubes above and below them. The partition R nearest the grate, made up of the plates 4', rests upon the arch f behind the grate, and there is a space between the top of the shell and said partition. The other partition T extends from the top of the shell downward. The heat must there= fore pass from the grate over partition R and under partition T and then up to the stack. The boiler is iuclosed at each end by the pairs of hinged doors L and L.

Having described my invention, I claim-- I. In a tubular boiler, the combination of two groups of vertical hollow headers set side by side to form the ends of the boiler, each header being connected at both its upper and lower ends with the header on each side of it, a plurality of substantially-vertical rows of inclined tubes which extend between the headers at one end of the boiler and those at the other end, and are connected with said headers, the tubes in each vertical row being oppositely inclined to those in the adjacent vertical row, a water-dome, and pipes connecting it with the upper ends of the head ers at both ends of the boiler, and pipes con- .necting said dome with the lower ends of some of the headers at both ends of the boiler, substantially as specified.

2. In a tubular boiler, the combination of the group of headers A A which are connected at both their upper and lower ends and constitute one end of the boiler, the group of headers A which are similarly connected and constitute the other end of the boiler and the tubes B B which extend from one group of headers to the other and are connected with them, said tubes being arranged in Vertical rows, of which the tubes in each-row are inclined in opposite directions to the tubes in adjacent rows, with the water-dome, pipes connecting it with the headers at both ends of the boiler, pipes connecting said dome with the lower ends of the outside headers in each group, and the vertical pipes at the four corners of the boiler, and connected with the upper and lower ends of the four outside headers, substantially as specified. j

3. In a tubular boiler, the combination of two hollow ends of the boiler, and tubes extending between and connected with said ends, and arranged in substantially-vertical rows, the tubes in one row being inclined oppositely to those in adjacent rows, a water dome, pipes connecting it with the upper parts of both of the boiler ends, and returnpipes connecting it with the lower parts of said boiler ends, substantially as specified.

4. In a tubular boiler, the combination of a steam-dome, a water-dome communicating therewith, headers communicatingwith said water-dome, inclined heating-tubes carried between the headers, and vertical circulat ing-pipes leading from the water-dome and communicating with the lower ends of the headers, substantially as specified.

5. In a tubular boiler, the combination of a steam-dome, a water-dome, inclined pipes connecting the water-dome with the upper ends of vertical headers, each header 'carrying two vertical rows of oppositely-inclined heatingtubes, said headers communicating top and bottom with each other, and located close together to form solid walls, vertical circulating pipes leading from the waterdome and communicating through horizontal pipes with the lower ends of the headers, substantially as specified.

6. In a tubular boiler, the combination of two groups of vertical hollow headers set side by side, the headers of each group being successively connected and communicating at both ends, and having closed openings at their backs, a plurality of substantially-vertical rows of inclined tubes which extend between the two groups of headers, and communicate therewith, the tubes in each vertical row being oppositely inclined to those in its adjacent rows, a steam-dome, a water dome connected therewith,inclined pipes connecting said water-dome with the upper ends of the headers,vertical circulating-pipes leadin g from the water-dome, and horizontal pipes connecting them with the lower ends of the headers, substantially as specified.
